what is the third law of newton?

Question

please help

Answer 1

Every has an equal and opposite reaction. That is if you hit a concrete wall with 50 Newtons of force the wall hits you back with 50 Newtons of force as well. But you are probally thinking my hand moves back but the wall does not... well my friend that is because the wall has more mass. So if a truck and a car collide the truck hits the car with x amount of force and believe it or not the car hits the truck with same amount. But y do we see the car move back more than the truck? Because the car has less mass than the truck. Good Luck.

Answer 2

Newton's laws of motion are three physical laws which provide relationships between the forces acting on a body and the motion of the body, first compiled by Sir Isaac Newton. Newton's laws were first published together in his work Philosophiae Naturalis Principia Mathematica (1687). The laws form the basis for classical mechanics. Newton used them to explain many results concerning the motion of physical objects. In the third volume of the text, he showed that the laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

Crudely stated, the three laws are:

An object in motion will remain in motion unless acted upon by another force.
Force equals mass times acceleration.
For every action there is an equal but opposite reaction

Answer 3

For every action, there is an equal and opposite reaction. This is the third law of newton...

Answer 4

'For every action, there is an equal and opposite reaction.' This is Newton's third law. [This should be under Physics not Maths!]

Answer 5

Every action has its equal and opposite reaction.

Examples:

When a gun fires a bullet, the gun recoils.
When a man throws stones from a boat in one direction, the boat moves in the other direction.
When the rocket engines are switched on, a powerful stream of gases comes out at the bottom and the rocket is propelled upwards.

Answer 6

every action has an equal and opposite reaction.
for example, when u walk, u do it by exerting some pressure on the ground in the backward direction to move forward. so that is the action, done by u. the ground inturn offers reaction by pushing ur feet in the forward direction, though u cant see that happen. so the action has got its reaction in the opposite direction.

Answer 7

"For every action, there is an equal and opposite reaction."
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

A variety of action-reaction force pairs are evident in nature. Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. But a push on the water will only serve to accelerate the water. In turn, the water reacts by pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on the water (backwards) is opposite the direction of the force on the fish (forwards). For every action, there is an equal (in size) and opposite (in direction) reaction force. Action-reaction force pairs make it possible for fish to swim.

Answer 8

They hit at the same speed?

Then if the truck was going 50 and the car was going 40.. then.. were they hitting with 2000mph of force or 90..

Answer 9

For every action there is an equal and opposite reaction.

Answer 10

every action action have a opposite reaction
